“…Some researchers adopted devices that are battery-less, like (Yahya et al, 2017), where a System in Package (SiP) was integrated with a 1Mb/s Radio transmitter and a non-volatile memory, to increase SoC efficiency and reduce cost. The SoCs use a utilized Energy harvesting Platform to supply the SoC and off-chip components in the IoT environment.…”

Most IoT applications usually contain a battery inside, which provides good mobility for the system, but also limits lifetime of the application in general. A lot of work concentrated on power saving algorithms for software, and hardware solutions to provide better results. The proposed solution uses a hybrid technique that enables the IoT system to save power by installing a secondary low current microcontroller to put sensors and other devices in sleep mode, and depending on the IoT device's application, it will be awakened by a needed trigger that is tuned according to the application (such as certain sensors readings, or time based trigger). This will provide high system flexibility.

“…These varying requirements and constraints make the design of systems-on-chips (SoCs) for the IoT a challenge. While many IoT systems are available in the literature [1][2][3][4][5][6], they often only offer point solutions for a single (or a class of) sensing application(s) without presenting the process followed to arrive at the different design decisions implemented, thus making it difficult for future designers to generalize their solution to other applications. To the authors' best knowledge, a methodology that uses an application's constraints to inform low-level circuit design decisions has not been presented yet.…”

This paper presents a top-down methodology for designing battery-less systems for the Internet-of-Things (IoT). We start by extracting features from a target IoT application and the environment in which it will be deployed. We then present strategies to translate these features into design choices that optimize the system and improve its reliability. We look into how to use these features to build the digital subsystem by determining the blocks to implement, the digital architecture, the clock rate of the system, the memory capacity, and the low power states. We also review how these features impact the choice of energy harvesting power management units.

Modern integrated circuits ranging from ultra-low power internet-of-things devices to high-performance processors cater to a wide spectrum of applications and notably aid in revolutionizing human lifestyle. For instance, wearable technology is a ubiquitous internetof-things application that has made great strides in the healthcare and fitness domain. High-performance chips such as graphics processing units enable an efficient computation platform for both graphics and non-graphics applications. However, along with the capability to support an ever-increasing scope of applications, these integrated circuits are also faced with a multitude of design challenges. In this work, we aim to address two such challenges: power consumption and tolerance to circuit or environmental variations, in two key markets of the semiconductor industry, namely internet-of-things and high-performance computing. Low-power operation is a crucial requirement in modern integrated circuits design. In self or battery-powered internet-of-things devices that are required to have a long lifetime, ultra-low power circuit design is of utmost importance due to limited battery capacities and efficiency of current energy harvesting technology. Ultra-low power operation increases the prospects of their sustainable or even perpetual operation. In the high-performance domain, advanced technologies and faster clock frequencies have led to an increase in static and dynamic power consumption. Low power consumption is necessary for longer battery lifetimes in portable devices like tablets and laptops. It is also crucial to reduce the thermal hot-spots and the need for heat-sinks in such processors. In this work, we investigate low power circuits and systems especially targeting the self/battery-powered applications.
